An object
(optional) A vector of indices on which to calculate the MSE.
Other arguments (not in use at this time).
logical, denoting whether to use the running predicted values.
Even though logistic regressions don't use the MSE on the y=0/1 scale, it can still be informative.
Note that the S3 method is mse.
